Final answer:
To convert nanoliters to microliters, use the conversion factor 1 nL = 0.001 µL, which is simply multiplying the number of nanoliters by 0.001.
Step-by-step explanation:
The conversion factor from nanoliters (nL) to microliters (µL) involves moving the decimal place because both units are in the metric system and are based on powers of 10. Specifically, 1 nanoliter is equivalent to 0.001 microliters since a nanoliter is 10-9 liters and a microliter is 10-6 liters. Therefore, to convert nanoliters to microliters, you can use the conversion factor 1 nL = 0.001 µL or simply multiply the number of nanoliters by 0.001.
